I'm sure its quite trivial to defeat googles algo, renaming the file, encrypting/compressing the file so it cant be accessed and wont match any checksums or hashes that they have on a list of naughty content.. plenty of options.

But why on earth host anything on an unreliable provider, that will mess with and delete your stuff without warning? That's a shit service. I wouldn't store anything significant on disks that get kicked around the floor, spilled coffee on, get chewed by cats that like to sleep near the PC.. so dont store anything with google either.

They are a shit company, divest yourself and anything important to you of everything google and sleep better.
